Chris,
 
Spark gap systems deliver the energy pretty quickly especially

Spark gaps work pretty well at high or low currents.  The large  coils mostly
are more efficient because there are smaller losses in the  transformer
and in the wiring, I think.  There may be some issues with spark  growth too,
I don't know.   Various folks have done various tests of  various things, but
yes it's difficult to remember it all sometimes, unless one is  thoroughly
organized.  Don't let it affect your sleep  :^)
 
It seems experimental work has slowed greatly among our
list members.  I haven't done any TC work lately either.  
 
I'll be looking forward to hearing about the results of your projects  as
you complete and test them.  
 
John
